Key Features
- 42-position dual-row Tiger Eye terminal strip with 0.050" (1.27 mm) pitch for high-density signal routing
- Cost-effective design without sacrificing contact reliability, reducing BOM cost in high-volume production
- Tape-and-reel (TR) packaging optimizes compatibility with pick-and-place automated assembly lines
- Male contact gender with board connector configuration for direct PCB-to-board mating
Applications
The TFC-121-02-F-D-A-K-TR is suited for cost-sensitive, high-volume PCB interconnect designs such as consumer electronics, telecom line cards, and embedded computing modules. Its 42-position dual-row layout on a 0.050" pitch enables dense signal routing in compact board-to-board stacking configurations. The tape-and-reel format makes it ideal for automated SMT assembly in production runs requiring consistent placement accuracy.

Frequently Asked Questions
What is the pitch and total contact count of the TFC-121-02-F-D-A-K-TR?
The TFC-121-02-F-D-A-K-TR features a 0.050" (1.27 mm) pitch with 42 positions arranged in a dual-row configuration, providing 21 contacts per row. This compact layout makes it an efficient choice for high-density board-to-board connections where signal count and footprint size are both critical design constraints.
Why is the TFC-121-02-F-D-A-K-TR a better choice than standard 0.100" pitch strips for dense designs?
The TFC-121-02-F-D-A-K-TR uses a 0.050" (1.27 mm) pitch compared to the 0.100" (2.54 mm) of traditional terminal strips, halving the footprint for the same 42-position count. This allows designers to reclaim board space or increase signal density in telecom, computing, and instrumentation boards, while the Tiger Eye contact design maintains reliable mating force across the full 42-pin interface.
Is the TFC-121-02-F-D-A-K-TR available in tape-and-reel for automated production?
Yes, the -TR suffix on TFC-121-02-F-D-A-K-TR specifically indicates tape-and-reel packaging, which is optimized for high-speed pick-and-place automated assembly equipment. This packaging format supports production volumes where manual placement of 42-position connectors would be impractical, ensuring consistent orientation and reducing assembly errors in high-mix, high-volume manufacturing environments.
